OPERATING MECHANISM FOR on-CUTTING MACHINES.

Specification of Letters Patent. Patented J 11119 29, 192( Application filed February 1, 1916. SerialNo. 75,583.-

To all whom it may concern: 1

Be it known thatI, JOSEPH S. TURINs, a citizen of the United States residing at Cleveland, in the county of duyahoga and State of Ohio, have invented certain new and useful Improvements in Operating Mechanism for Ice-Cutting Machines; and I employed for rotating a crank shaft operating ice cutting saws.

With the foregoing and other objects in view this invention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and claimed.

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters designate like and corresponding parts throughout the several views, and in which a Figure 1 is a side elevation of the ice cutting machine showing parts broken away, and

Fig. 2 is a fragmentary horizontal section of the ice cutting machine.

Referring more particularly to the drawings, 1 designates the supporting platform or base of the ice cutting machine as an entirety, which has a prime mover 2 mounted thereon. The prime mover 2 may be either an electrical motor, a gasolene engine or any other desired type of prime mover, this feature beingleft to the desire of the person manufacturing the device.

The prime mover 2 has a main power shaft 3 this shaft will carry a conventional gearing (not shown) so that rotary movement may be transmitted through the medium of gear 8 to the shaft 9.

The shaft 9 extends transversely to the shaft 3 and is rotatably supported by a suitable pillow block 10. The shaft 9 has a operatively connected thereto and g beveled gear 11 mounted thereupon which meshes with the beveled teeth formed upon a gear member 13 rotatably mounted upon a shaft 1 1. The gear member 13 has ordinary gear teeth 17 formed thereupon which mesh with a pinion 18.

The gear .18 meshes with a gear21, which is mounted upon a crank shaft 22. The crank shaft 22 is positioned at the rear end of the-supporting platform 1 and is rotatably supported by suitable bearings 23 and has ice cutting saws 25 connected thereto and extending downwardly through openings 26 which are formed in the supporting base 1. The saws 25 are loosely connected to the crank extensions of the crank shaft 22, so they will maintain a vertical position at all times dur ing the rotation of the crank shaft and movevertically through the ice for cutting the same. i p

The supporting platform 1 has hangers 27 connected to it under surface adjacent I the rear ends, which hangers rotatably sup- 7 port the drive axle 28 of the ice sawing machine. The axle 28 has wheels mounted thereon for rotation with the axle, which wheels have a plurality of spaced spurs extending about their peripheries,jfor biting into the ice for propelling the ice sawing machine. extend annularly about the rims of the wheels 29 and are provided for preventing sidewise slipping of the wheels and the ice sawing machine.

The axle 28 has a relatively wide ratchet wheel 32 mounted thereon intermediate its ends, the peripheral ratchet teeth 33 of Outstanding rings or flanges 31 which are provided for coaction with apawl 3a carried by a bar 35. The bar 25 has its upper end mounted upon a pin 36, which pin is eccentrically connected to the ear member 13, as clearly shown in Fig. 1 0 the drawings, so that during the rotation of the gear member 13, the pawl 34- w'ill be brought into and out of engagement with the ratchet teeth 33, and rotate the ratchet 32 and consequently the axle 28 by the rotation of the ear member 13 which member also acts to transmit the power to the crank shaft 22, thereby controlling the rotation of the axle 28' with'the rotation of the crank shaft 22,

for properly controlling the speed of the forward movement of the ice sawmg ma,-

chine.

A shifting rod 40 which is provided with ative relation to the ratchet wheel 32, and

further providing means for guiding vertical movement of the bar when in operation,

The machine is steered,

ice sawing through the mediumof-a steering post which projects vertically through the supporting platform 1, and has a steering wheel s5l-mounted upon its upper end. The steering post 50 is operatively connected to the axlebearings 54, of the front axle thus permitting the .skein or truck 57 to be swung for guiding ,thedirection of travel of'the ice. sawing machine, as is ordinary 1n the j construction of steering mechanism of this nature.

The steering post 50has an arm 60 mounted thereon, and positioned above the platform 1, which arm has an opening 61 formed thereinadjacent its outer end. The arm 60 travels above the upper surface of a quadrant 62, which is carried in a horizontal plane 'by a suitable supporting structure in- The quadrant 62 is provided with a plurality of spaced openings,through which a pin passed through the opening 61 maybe passed for holding the arm in various adjustedpositions. about the quadrant for holding the steering post 50 against accidental movement, and preventing the'slipping of the steering wheels of the ice cut- .ting machine during travel over an ice field. The supporting wheels 66 which are mountedkupon the front axle 55 have peripheral flanges 67 formed centrally of their rim sections which are provided for preventing lateral creeping or slipping of the wheels.

From the foregoing description taken in connection with the accompanying drawings the advantages of. construction and of the method of operation of the improved ice cutting machine will be readily apparent to those skilled in the art to which this inven- 7 tion appertains and, while in the foregoing description, the principle of the operation of this invention has been described together with various features of construction, it is to be understood that certain minor features of construction combination and arrangement of partsmay be altered to suit practical conditions provided such alterations are comprehended withinithe scope of what is claimed. r V 1 l Vhat is claimed is r In propelling means, a rotatable gear, an axle mounted below thegear, a ratchet wheel secured 011 said axle, a bar eccentrically .se-'

-cured at its upper end to the gear, a control rod mounted for movement toward and a-wa from the. ear and rovided with an .eye slidably receiving said bar so as to. guide the same during reciprocation thereof, the lever serving to hold the harm adjustment towardand awayfromthe ratchet wheel, .and apawl rigidly secured to said bar adjacent the lower end thereof and adaptedto engage the ratchet wheel so as to impart in-
